Dp. Foster, CRITICAL EXPONENTS FOR A SELF-INTERACTING, DIRECTED POLYMER WITH ADSORPTION, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 47(2), 1993, pp. 1441-1444
We present an exact determination of the correlation-length exponents
as well as an accurate numerical estimation of the bulk and surface en
tropic exponents at the ordinary and special theta points for a direct
ed-polymer model. The numerical results were obtained using an exact e
numeration of walks up to 29 steps.
